Why Our Aquatic Invertebrates Need Calcium

Updated: Jul 18, 2023

Calcium is an essential nutrient for all living organisms, including aquatic invertebrates. It plays a critical role in maintaining their structural integrity and supporting vital physiological functions. Calcium is particularly important for aquatic invertebrates, as they rely on external sources to acquire this essential nutrient.

In this blog post, we will discuss how feeding calcium to aquatic invertebrates benefits them and why it is necessary for their survival.

  1. Shell formation

Many aquatic invertebrates, such as snails, clams, and crustaceans, rely on calcium to form and maintain their shells. Calcium carbonate is the primary component of most invertebrate shells, and a deficiency in calcium can result in weakened or deformed shells.

By feeding calcium-rich foods to aquatic invertebrates, we can help ensure that they have the necessary building blocks to form strong and healthy shells. This is particularly important in aquarium settings, where calcium levels can fluctuate, and invertebrates may not have access to natural sources of calcium.


2. Muscle function

Calcium also plays a critical role in muscle function in aquatic invertebrates. It is necessary for muscle contraction and relaxation, as well as maintaining the proper pH balance within muscle cells.

Invertebrates with calcium deficiencies may experience muscle weakness or spasms, which can impair their ability to move, feed, and defend themselves. By providing them with calcium-rich foods, we can help ensure that their muscles function properly and support their overall health and well-being.

3. Nervous system function

Calcium is also important for the proper functioning of the nervous system in aquatic invertebrates. It is involved in the transmission of nerve impulses and the release of neurotransmitters, which are essential for communication between nerve cells.

Invertebrates with calcium deficiencies may experience impaired nerve function, which can affect their behavior, feeding, and other vital functions. By feeding them calcium-rich foods, we can help support their nervous system function and overall health.


4. Reproduction

Calcium is also essential for the reproductive health of many aquatic invertebrates. It is necessary for the formation of eggs and sperm, as well as the development of embryos.

Invertebrates with calcium deficiencies may experience reproductive failure, including the inability to produce viable offspring. By providing them with calcium-rich foods, we can help support their reproductive health and ensure the survival of their species.

In conclusion, feeding calcium to aquatic invertebrates is crucial for their survival and well-being. It supports shell formation, muscle function, nervous system function, and reproductive health. By ensuring that these organisms have access to the necessary nutrients, we can help maintain healthy and vibrant aquatic ecosystems.


Why KatsAquatics?


Maintaining the proper balance of nutrients and water quality in a fish tank is essential for the health and well-being of the fish and other aquatic organisms living within it. Calcium is an essential nutrient for many species of fish, but the type of calcium supplement you use can have a significant impact on the overall water quality in your tank. Now, we'll discuss why KatsAquatics Calcium, which does not dissolve into water, is better for fishtanks than calcium that affects water quality.

  1. Maintaining water quality

The primary advantage of using KatsAquatics Calcium is that it does not dissolve into water. This means that it will not affect the pH or other water parameters in your tank, which can be critical for maintaining the health of your fish and other aquatic organisms. Some types of calcium supplements can cause a buildup of dissolved solids in the water, leading to issues with water quality and potential harm to the inhabitants of the tank. Sudden swings in water parameters can also negatively affect more sensitive fauna such as discus, caridina shrimp, and fry.


2. Preventing algae growth


Another benefit of using KatsAquatics Calcium is that it can help prevent algae growth in your tank. Algae thrive in environments with high levels of dissolved nutrients, such as nitrate and phosphate. When you use a calcium supplement that dissolves into water, it can contribute to the buildup of these nutrients, which can lead to excessive algae growth.


3. Improved absorption


Feeding bioavailable calcium (KatsAquatics) directly to aquatic invertebrates ensures that they receive the maximum amount of calcium available. When calcium is added to the water, it must first dissolve into the water before the invertebrates can absorb it. This can be a slow and inefficient process, and not all of the calcium may be available for uptake by the invertebrates.


4. Customizable dosing


Feeding bioavailable calcium directly to invertebrates also allows for more precise dosing. Different species of invertebrates have varying calcium requirements, and feeding calcium directly to them allows for a more targeted approach. By providing bioavailable calcium in the appropriate amount, you can ensure that each species receives the necessary amount of calcium without over or under-dosing.


5. Reduced waste


Adding calcium directly to the water can result in a buildup of dissolved minerals, which can contribute to waste buildup and other water quality issues. Feeding bioavailable calcium directly to the invertebrates can reduce the amount of unused calcium in the water, resulting in less waste and a healthier environment for your aquatic organisms.


6. Improved growth and health


Feeding bioavailable calcium directly to invertebrates has been shown to improve their growth and overall health. By providing a readily available source of calcium, invertebrates can better meet their nutritional needs, which can result in stronger, healthier organisms that are more resistant to disease and other stressors.
